Blender contest- "The game"

It's been a moment. Once again I got myself into contest (can't help it- competing is something I can't really live without), this time it's polish blender community portal held contest with "the game" being a title. As long as picture is even remotely related to the game- it can enter. Since it's being made for fun I've decided to go as kitschy as only possible and based concept on life vs. death scheme, with angel and death playing chess. You can see the basic sketch (actually the very first one I did for this project) and base, untextured meshes (before any sculpting). I'll be grateful for all hints and comments you can give me.
